AUTOMOBILE-PUMP.

Specification of Letters I'atent.

Patented Mar. a, 1913.

Application filed April 26, 1912. Serial No. 693,410.

a new and Improved Automobile-Pump, of

which the following is a full, clear, and exact description.

The invention relates to that form of automobile pumphaving means forattaching it to an automobile wheel, and for actuating the pump by therevolution of-the wheel for the purpose of inflating the tires.

An object of our invention is to provide a pumping attachment of thecharacterreferred to, which is attachable to any wheel regardless of thesize and form of the hub,

or the absence of any projection of the, hub

beyond the face of the wheel.

A further object is to provide means so designed as to permit ofsecuring the attachment to such Wheels as are provided with large brakedrums.

A further object is to simplify theconstruction of pumps of theindicated character, to the end that few parts will be involved, andwhereby the attachment can be secured to the wheel and detachedtherefrom quickly and conveniently.

The distinguishing features of the invention and the importantstructural elements in the preferred embodiment which is given as anexample, will. be more particularly explained in the specificdescription hereinafter to be given. 1

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views. v

Figure 1 is a side elevation of our improved pump and appurtenances,showing the same in position for use; and Fig. 2 is a horizontal sectionof the pump onabout the line 22 in Fig. 1, but showing the member havingthe securing arms of the attachment moved approximately 90 degrees fromthe position shown in Fig. 1.

In constructing-an attachment in accord ance with the illustratedexample, a flat ring 10 is provided, the open center 11 of which is of asize to pass freely over any hub of standard cars, the inner face 12 ofthe ring being adapted to lie close against the outer face of the wheel13. The ring 10 is provided with two or more arms 14 which extendreferably on radial lines and at d ametricaly opposite points. .The armsmay be connected in any suitable manner with the ring 10. In theillustrated example these arms are integral with the ring; they extendto a point sufliciently distant from the hub for the .ends 15 to reachbeyond the brake drum 16 of the wheel, regardless of the size of saiddrum. The outer ends of the arms 14 carry suitable means for clampingengagement with the wheel; in the illustrated example the devices areadapted to engage with the spokes 17 of the Wheel, the

clamping device shown consistin of a hooked bolt 18 having a threaded sank 19 that extends from the ends 15 of the arms 14, and carries levernuts 20. The ring 10 supports a loose ring 21 carrying the 'air pump 22,saidring 21 in the illustrated example being received on the reducedinner end 23 of an outer ring 24, Which'is secured to the ring 10. Inthe illustrated example, 7

the outer rin 24 is attachable to the ring 10 and readily detachabletherefrom by means of screws 25 or their equivalents.

The outer portion of the ring 24 has a diameter sufficiently larger-thanthe inner reduced portion 23 to form a shoulder 26, so that the saidring 24 constitutes a retainer for the loose ring 21, .and said ring 24constitutes an actuating member for the pump 22, and for this purposesuitable teeth 27 are formed on the outer periphery of the ring 24, sothat the latter constitutes a gear Wheel which in the illustratedexample is a spur gear; it meshes with a pinion 28 that is keyed to theinner end of the crank shaft '29, said crank shaft desirably operatingin same in small compass when not in use, and

to this end the loose ring 21 is formed with feet 33 projecting outwardparallel with the axis of the said ring to constitute brackets, and thebase of crank case 30 of the pump is formed with a flange 34 at eachside, said flanges being secured, as by bolts 35, to the feet 33 of theloose ring 21, so that the pump body is thus held rigid with the saidloose l he described construction, as will be obvious, permits therotation of the rin l0 and the outer ring 21 with the wheel of the car,and relatively to the loose ring 21 and the pump. To hold the pump andthe ring valve 40 and with a discharge provided with a length of hose41, which in practice, is connected with the inlet valve of the tire tobe inflated.

It is not of prime importance that the member 10 be in ring form, otherthan its having a bore or eye to pass over any projecting hub onstandard cars, and its configuration may vary so that it constitutes aplate to lie against the outer face of the wheel at the inner ends ofthe spokes. The described member 10 and the ring 24 are in fixedrelation to each other, it will be observed, and constitute, therefore,a unitary, revoluble device forming, with the arms 14 and the clampbolts, a centering device and securing means having a bore of a diameterto pass over any projecting hub, andserving to hold the attachment tothe wheel independently of the hub and axle spindle. In addition, thesaid revoluble unitary device constitutes a retaining means for thepump, by reason of clamping the loose pump-carrying ring 21 in what isin effect a peripheral annular groove, and furthermore by reason of thegear teeth 27, co-axial with the wheel, the described revoluble deviceconstitutes the prime mover of the pump-actuating gear.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. A pumping attachment for automobile wheels, comprising a revolubledevice, a pump-carrying member loose on said revoluble device, andoperating connections between the revoluble device and the pump, saidrevoluble device having a bore or eye to pass over any projecting hub aswell as to fit wheels without projecting hubs, and comprising an innermember to lie against the face of the wheel and carrying wheelclampingarms, and an outer member having gear teeth to constitute the primemover of the pump-actuating device, said actuating device including alsoa pinion in mesh with the said gear teeth, a crank shaft operating inthe pump casing and carrying said pinion, means connecting the crankshaft and the pump piston, and means for holding the pump and itscarrying member against turning with the revoluble device.
